摘要:
A silver halide photographic material having one or more silver halide emulsion layers formed on a support is disclosed wherein at least one of said silver halide emulsion layers contains at least one cyan coupler of formula (I) dispersed therein with the aid of a high-boiling organic solvent having a dielectric constant of not more than 6.0: ##STR1## (wherein R.sub.1 is a straight- or branched-chain alkyl group having 2 or 4 carbon atoms; X is a hydrogen atom or a group capable of leaving upon coupling reaction; and R.sub.2 is a ballast group).
